Specification of Letters Patent.

To all wliom t may concern Be it known that I, GEORGE W. B EADLE, acitizen of the United States, residing at Bayonne, in the county ofHudson and Siate of New Jersey, have invented certain new and usefulImprovements in Machines for Coating Cartons; and l do hereby declarethe following to be a full, clear, and exact description of theinveition, such as will enable Others skilled in the art to which itappertains to make anduse the same.

This invention relates to improvements in para'liining machinesl adaptedto coat paper cartons orthe like, and has for its object to provide asimple mechanism for this purpose that will melt and keep the parafiinat a proper temperature, and will automatically coat the carton withcertainty and celerity.

A further Object is to provide a simple and eliicient means forreceiving the cartons and conveying them away from the machine afterthey have been coated.

With these and other objects in View the invention consists in the noveldetails of construct-ion land combinations of parts more fully.hereinafter described and particnlarly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all theviews v Figure 1 is a side elevational view of my improved machine; Fig.2 is a top plan view of the same; Fig. 3 is an end elevational viewlooking toward the right, as shown in Fig. 1; Fig. 4 is a longitudinalsectional view of the machine; Fig. 5 is a cross sectional view taken onthe line 5 5 of Fig. 4, and looking in the direction of the arrows; Fig. 6 is an enlarged detail view showing the meansffor delivering thecartons to and .the means for taking the cartons from the paratliningwheel; Fig. 7 is a sectional view taken on the line 7 7 of Fig. 6; and,Fig. 8 is a diagrammatic plan view of the system of piping.'

The supporting frame of the machine comprises the upright supports 1, 2and 3, Figs. 1 and 4, connected by the angle bars 4 and 5, Figs. 4 and'5, and the cross beams 6 and 7 located above the bars 5 and extendingacross the same.

which is held against movement within the water tank by the angle stays14, thereby .providing between the water and the paraflin tanks awaterand steam space or jacket 15.

16 indicates a second water tank mounted on the angle bars. 5 andlocated below and to one side of the water tank 11 as shown. This tank16-is also rigidly held in position by the cross angle bars 17 and hassuspended therein on the angle bars 18 (see Figs. 4

and 5) a .second paraiiin tank 19, also surrounded by a water and airspace. Gages ,20 and 21, Fig. 2, are connected to the water tanks 16 and11 respectively, for showmg at all times the amount of water therein.'

Suspended under and adapted to heat the water respectively within thesaid water tanks 16 and 11 for the purpose of melting the paraffin arethe gas burners 22 and Q3, which receive their supplies of gas throughthe gas pipes 24 and 25 connected to. the main feed pipe 26. Theseburners are controlled by the valves 27 which are so adj usted as toalways keep the temperature within the paratiin tanks 13 and 19 a littleabove the melting point of the paraffin.

,The parailin within the tank 19 is preferably kept at the level shownin Figs. 4 and 5, and when it falls below this level the valve 28,mounted within the outlet 29 in the bottom of the paratin feed tank" 13will be automatically opened by the iioat 30 and its connections 31 and32 with said valve allowing paraffin to flow from the feed tank throughtheP spout 33 to the tank 19. 34 indicates a spring surrounding thevalve stem for assisting the float to properly seat lthe said valve 2Sfor cutting olf the flow after the tank 19 has received its propersupply.

A circular guide casing 35 which performs a function to be described, isheld within the paratlin tank 19 by the stays 36.

Mounted on the shaft 38 in the angle bars 4, and adapted to revolvewithin the parmachine as will now appear.

aiiin tank 19, is a paraffin Wheel 39,*which wheel is of skeletonconstruction and 1s procarriedby the shaft 46 on which is mounted theplate 47 which normally prevents the cartons from entering said opening45. The r'od or' shaft 46 also carries the rearwardly extending spring49 adapted to contact with the cartons 43 at intervals and to force themforward. The top plate 10 is pro- Y vided with the brackets 50 .in whichthe 1 elements forming the pockets 42 of the parj lsha-ft 46 turns, andthe wheel 39 carries pins 51 adapted to strike the rod 48 `at intervals,to rock the shaft 46 thereby raising the plate 47 and causing thesprings 49 to force from thedrawings. After the cartons, one afteranother, are -thus delivered into the pockets 42,'they arecarried'around by the wheel 39 in the direction of the arrow, im-

mersed in the paraiin 90, and'after being,v thus thoroughly coatedinside an'd out with parafn, they are brought out on the otherv side ofthe wheel, having been guided and' held in their passage by the circularcasing.'

35. After the cartons have completed their passage through the paraffin,they are automatically carried out of the machine by thel means now tobe described. l

Rigidly mounted betweenvthe brackets 52 and 53 carried by the angle bars4 is a bar 54, from which is suspended a plurality of stripping rods 55that project between the aflin wheel 39, see Figs. 4, 5, 6 and 7.

A bracket 56 Figs. 1, 2 and 3,- carried by the end support 9, holds asmall electric motor 57 for operating the machine. This motor drives achain 58,passing over a .sprocket wheel 59, mounted on the outer end ofa shaft 60, which shaft has a bearing in a bracket 61, Fig. 2, held tothe end of the machine. A pinion 62, Fig. 3 mounted on 'the shaft 60,drives a gear 63 held on the outer end of a shaft 64, which shaft isalso mounted in bearingson the bracket 61.

65, Fig. 1, indicates a worm mounted on I the inner. end of the shaft 60for driving the Worm gear 66, mounted on the inner end of a stud shaft67, extending across t-he shaft 60, and which, is also held in bearingsin the bracket 61. A sprocket 68, Fig. 2, is mounted on the outer endofthe stud shaft 67 for driving the chain 69, for transmitting powertothe sprocket wheel 7 O, mountT ed on the outer end of the shaft 38,for revolving the paraffin wheel 439. The shaft 64 has also mountedthereon a sprocket 71 for transmitting power, through the chain 72, tothe sprocket wheel 73 mounted on the outer end of va shaft 74 journaledin bearings on the framework of the machine. The shaft 74has mountedthereon, within the frame of the machine, two sprockets 75 overwhichgpass chains 76 fork conveying the cartons after they have beencoated with paraffin, to an apparatus in which they. are dried. f

From the mechanism just described it will be clear that as power istransmitted from the motor 57 to turn the wheel 39, the paraffin coatedlcartons will be ,forced from the pockets 42 by `the stripping rods 55,and over on to` the conveying chains7 6, which will'carry 'them to asuitable drying chamber not shown.

Small spaces 77 are preferably left be` tween the casing andthe Watertanks l1 and the supply pipe 81 communicating with tank 11 is opened,water will be admitted to the tank 11and after filling the same willpass out through the pipe 82 near its top, and through the pipe 83 intothe water tank 16 until it has reachedits proper level as shown on thewater gage 20,when the supply valve 80 may be closed. When the tanks areto be emptied, the valves 78 and 79 are opened and water will flowthrough the pipes 83 and 84 and waste pipe 85 to the sewer.

The operation of the machine will be clear from theforegoing but may bebriefly summarized Aas follows Supposing the water and paraffin tanksare filled and the gas burners are keeping the paraflin at its propertemperature. The par-Hin wheel is revolved in the direction shown by thearrows, in Fig..4, by the motor through the chain 58, sprocket 59, shaft60, Worm 65, worm gear 66, shaft 67, sprocket 68, chain 69, and sprocketwheel 70, and the conveyer chains are operated by the pinion 62, gear63, shaft 64, sprocket 71, chain 72, sprocket 73, shaft 74, andsprockets 75. In revolving, the pins 51 on the wheel 39 successively-contact with the operating rod 48, and through the shaft 46 move theplate 47 out ofthe path of the cartons and allows them to drop from thechute 44 intoA the pockets 42 of the paratlin wheel. During each rockingof shaft 46 the two rearwardly extending springs 49 thereon contact withthe succeeding carton, (see Fig. 6) and hold it until the rod 48 isagain operated by a piul. '.l`he cartons on the paratn wheel are "guidedand held'by" the casing 35. while in the paraiiin bath, until they arethoroughly coated'.l .They are then removed by contactingv withthe rods55 and delivered to the conveyer chains 76, which chains travel slowlydirectly over the paraiiin bath, thereby allowing the surplus paraiin todrain back into said bath. From the paraffini machine the cartons areconveyed by the conveyer vchains to a drying machine chamber not shownwhere they are thoroughly dried. ]It is obvious that those skilled inthe art 'may .vary the details of construction and,.- 215 fromthe spiritof myinvention, and therev yfore I do not wish to be limited to theabove.. disclosure `except as may be required by the;
